KEY-FASTENER.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed August 3, 1914. Serial No. 854,754.

To all whom it may concern:

Be it known that we, J osnrn A. GLowIN- em and EDWARD SLADEK, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Key-Fasteners, of which the following is a specification.

The object of our invention is to provide a device which may be secured to a door adjacent the key-hole opening of the lock and which is so constructedthat a portion thereof may be' inserted through the ring of the key when in place in the lock and will hold the key against removal therefrom.

A further object is to so construct the device that it may be adjusted to accommodate various operating conditions and keys of various lengths. e i

With other objects in view, which will be referred to, our invention consists in the peculiar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawing and more particularly pointed out in the appended claims.

In the drawing: Figure .1 is a view in side elevation of a portion of a door adjacent the lock with our device illustrated in an operative relation. Fig. 2 is a transverse vertical sectional view through the disclosure in Fig. 1 to illustrate our improved key fastener in end elevation.

The supporting member of our improved key fastener comprises a base plate 1 which has an arm 2 projecting from the face thereof and in use this supporting member is secured to the door adjacent the key-hole opening in such relation that the arm 2 extends at right angles to the facing of the door and lies in approximately the same horizontal plane as the key, the screws 3 being illustrated in the present instance as the means of securing the base plate 1 to hold the supporting member in place. The arm 2 has a slot 4: formed throughout the greater part of its length.

A bracket member 5 is constructed to be adjustably mounted on the arm 2 and this mounting is accomplished by passing the clamp screw 6 through the slot 4 and into the lower end of the bracket member 5, this clamp screw and the relatively long length of the slot 4 permitting the bracket memher 5 to be swung around its pivot on the clamp screw 6 and 7 also to be adjusted toward and away from the face of the door. A slide bearing 7 is provided through the outer free end of the bracket member 5 and the locking rod 8 is mounted in this bearing to have endwise sliding movement, the set screw 9, which may have the head thereof made hexagonal, winged or of any other desired configuration to permit manual turning, being provided to hold this locking rod 8 at the position to which it may be adjusted endwise.

In use, the device is fastened to a door adjacent the key-hole opening to the look, as better illustrated in Fig. 1, the locking rod 8 is moved endwise to the position indicated in dotted line, the key is inserted within the key-hole and then by moving the locking rod in an opposite direction through the bearing 7 and adjusting the disposition of the bracket member through the medium of the clamp screw 6 the parts may be brought to such a relation that the locking rod 8 is received through the ring of the key, this position being better illustrated in Fig. 2, and by turning the set screw 9 down against the locking rod 8 the parts will be held in the position to which they have been adjusted and the key is secured against accidental or manual removal from the key-hole until the fastening device is again manually manipulated.

From the foregoing it will be seen that we have provided a key fastener which is so constructed that when once adjusted to a position to fasten the key, this key is held against removal either accidental or manual regardless of whether the key may have been turned to lock the door or may have been merely inserted in the key-hole, and also it will be seen that in this way possibility ofthe key being shoved from the lock and the lock manipulated by a key inserted from the outside is precluded, further the key is always retained at a point to be accessible and also accidental displacement of the key through the swinging of the door or from any other cause is prevented.

While We have herein shown and described one specific form of our invention and but a single means of adjusting the parts and holding these parts in their adjusted position, it will be understood that slight changes might be made in the form and arrangement of the several parts without departing from the spirit and scope of our invention, and hence we do not wish to be limited thereto except for such limitations as the claims may import.

WVe claim 1. A key fastener comprising a supporting member, a bracket member adjustably carried by said supporting member, a locking member slidably mounted in said bracket member to be capable of sliding movement to a relation to engage the key and to a disengaged relation, and means to secure said locking member rigidly in any desired adjusted relation.

2.. A key fastener comprising a supporting member to be secured to a door adjacent the keyhole opening to the lock thereof, a bracket member, a connection between said supporting member and bracket member so arranged that the bracket member may be adjusted with respect to said supporting member and rigidly secured in the adjusted relation, and a key locking member slidably mounted in said bracket member to be en gaged and disengaged with the key as the occasion may require.

3. A key fastener comprising a supporting member to be secured to the door adj acent the key-hole opening to the look there of, a bracket member carried by said supporting. member, a locking member carried by said bracket member to have movement with respect thereto to a position to engage within the ring of the key and hold the key against removal from the keyhole, and means to secure the locking member rigidly located in the desired relation.

4. A key fastener comprising a supporting member to be secured to the door adjacent the keyhole opening thereof, a bracket member mounted on said supporting member to have one end thereof adjustable in a direction toward and away from the face of the door and in a vertical direction, means to secure said bracket member rigidly in the desired relation with respect to the supporting member, and a locking member carried by said adjustable end to be received through the ring of the key to hold the key against turning movement and against removal from the key-hole.

5. A key fastener comprising a supportwith a slot therethrough, a bracket member, a clamp screw received through the slot of said supporting member into one end of said bracket member to permit adjustment of the bracket member, and means carried by the free end of the bracket member to be engaged with the key to prevent turning movement thereof and removal from the lock.

6. A key fastener comprising a supporting member consisting of a base to be secured to the door adjacent the key-hole opening thereof and an arm positioned to extend from said base portion and provided with a slot therethrough, a bracket member, a clamp screw received through the slot of said supporting member into one end of said bracket member to permit adjustment of the bracket member, a slide bearing provided in the free end of the supporting bracket, a locking member received through said bearing to be capable of movement to a position to engage through the ring-of the key and hold the key against turning movement and against removal from the key-hole, and a set screw to hold said locking member in its operative relation.

7. A key fastener comprising a supporting member to be secured to a door adjacent the keyhole opening thereof, a bracket member mounted on said supporting member to be capable of adjustment with respect thereto, means'to secure said bracket member rigidly in the desired adjusted relation, a key-locking member slidably mounted with respect to said bracket member to be engaged with and disengaged from the key v and means to secure said key-locking member in any desired relation.

In testimony whereof we affix our signatures in presence of two witnesses.
